I enjoyed this fun, well-produced promotional video which I believe is about these libraries.
However, the title: “Police Library Girls,” seems disrespectful to me. How about “Police Librarians”? If the department’s professionals were all men, would it have been titled “Police Library Boys”? Somehow I doubt it.
What an interesting sort of special library, though. Perhaps the ideal police librarian would have a background in law librarianship?
